What phenomenon causes the tremendous outward-moving shock wave in a Type II Supernova?
Answer
The imploded core becoming incredibly stiff and effectively 'bouncing' after reaching nuclear density
When the collapsing core is squeezed past nuclear density, it becomes extremely stiff, causing the infalling matter to halt suddenly and 'bounce,' generating the outward shock wave.
